Abstract:
A novel method and apparatus inspects liquid crystal display. The method and apparatus for inspecting the flat display device scans at least one signal wire by using a magnetic sensor and detects a resistance change of the magnetic sensor to perceive a short in the signal wire. Pixels can be tested using an array of magnetic sensors configured such that each sensor in the array is smaller than the pixel.
Abstract:
A method for manufacturing a substrate of an analytical sensor and the substrate thus prepared are disclosed. The method for manufacturing the substrate of the sensor application according to the present invention is characterized in that it comprises (a) the step of preparing a dispersed solution of nanoparticles, which are stable in a volatile organic solvent due to surface modification of nanoparticles having a pre-designed certain size on the nanometer level with an organic functional group (b) the step of preparing a single layer film of nanoparticles surface-modified with the organic functional group on the interface using said dispersed solution of nanoparticles on the basis of the Langmuir-Blodgett method, and then transferring said single layer film of nanoparticles to the substrate; and (c) the step of coating the substrate to which said single layer film of nanoparticles is transferred, with the metal thin film by means of the vacuum vapor deposition, and then optionally removing nanoparticles to manufacture a nanostructure to be used as the analytical sensor using optical characteristics. According to the method for manufacturing the substrate of the sensor application according to the present invention as above, the nanoparticles can be uniformly fixed on the solid substrate having a great area above 10×10 cm2 using the Langmuir-Blodgett method, and by such method the size, distance and shape of nanoparticles can be controlled to manufacture the nanostructures to be used as the analytical sensor, which is possible to reproduce and mass-produce. When the sensitivity property of the sensor is measured using the nanostructure substrate, thus produced, to be used as the analytical sensor, it can be identified that the sensitivity can be highly improved.
